UNITED STATES PATENT" OFFICE FLOATING RING SPINNING Edgar G. Guenther, Kingsport. Tenn, assignor to Eastman Kodak Company, Rochester, N. Y., a corporation of New York 7 Application June 22,1935, Serial No. 27,921 a Claims. (01. 118-60) ning machines. Another object of my invention isto provide a simple type of spinning device which can be used in spinning artificial silk di may em the spinning cabinets. Another'object of my invention is to provide a spinning devi li, iii which doil'ing can be readily accomplished.

answer Object of my invention is to provide a simple of spinning mechanism which can readily made and assembled and which is for use in the various spinning operatioiisiieces'siary with artificial silk, and other oba'ill appear mm the following specificatiofi;" thf novel features being particularly pointed out at the end thereof.

Iii mean types of spinning, such as cap spinning'J-andring and traveler spinning each type has certain advantages and disadvantages. Cap

' spinning is generally used for spinning yarn coming directly from a spinning cabinet because it permits rapid domlng. Caps for cap spinning are expensive and have other disadvan tages tirllich my present invention is designed to overclim'e by making a lighter weight and less expensive device which can also be readily dofled. While primarily intended for spinning machines my invention may if desired be applied to other types of machines, as for instance twisting machines.

Coming now to the drawing, wherein like reference characters denote like parts:

Figure l is a part side elevation and part section of a floating ring type of spinning device constructed in accordance with and embodying a preferred form of my invention.

Figure 2 is a view similer to Figure 1 but of a slightly modified form of device.

Figure 3 is an enlarged sectional view through a ring and ring support such as are shown in the preceding fi s.

Figure 4 is a fragmentary plan view showing a portion of the ring support or seat.

My improved form of spinning device can be briefly described as a ring which may rest in a seat in a support when not in use and which, when in use, floats in the seat. That is to say, the yarn passes around a smooth periphery on the ring, and the rapidly rotating bobbin causes the yarn to exert a forceupon thering so that it will rise from its seat a short distance and be frame partially shown at 8.

more or less suspended y the yarn as theyarn is wound upon the bobbin. 1

More specifically, in the embodiment of my invention shown in Figure 1, a bobbin i having the usual flanges 2 and 3 is mounted on a base 4 having a driving contact with a whorl 5 which may be driven in the usual manner. The whorl 5 and the bobbin I may be verticallymoved by the traverse rail 6 as is customary in such machines,- this traverse rail being mounted above the stationary rail vi which may be attached to the machine As .thus far described, the construction is .well. knownin the spinning art.

Also attached tothe machine frame 8 is string support 9 having a flange bevelled inwardlyat ll, forming a seat for a ringi L, As best shown in Figure 3, the ring ii is provided with an outwardly projecting flange i2, terminating in a smooth, rounded yarn engaging periphery IS.

The support 9 may be carried by a bracket it supported by the machine frame 8, and the support 9 as best shown in Figure 4 may be provided with a slot l5 preferably extending radially through the supporting member and preferably having smooth edges rounded at the corners ll so as not to damage yarn passing through the slot.

In the form shown in Figure 1 the support 9 is fixed relative to the bobbin 1 which, as above explained, is adapted to move vertically up and down through the support and through the ring Ii.

If desired, as a modification of this form of my invention as shown inFigure 2, the ring 9 may be carried by bracket I! supported by a bar II which can be moved up and down by a rod I! which moves the traverse rail I8. In this case the bobbin i and whorl 5 are together in such a manner that their only motions with respect to the support 9 are rotational and as a vertical traverse. The shaft may be fixed as by a pin II to a stationary rail 22 attached to the machine frame I.

Thus it will be seen that it is only necessary to have the bobbin l and the ring it move rel-'- ative to each other, and it is immaterial which one of the two members is the part which is moved.

The ring H, as can be seen from Figln'e 3, is a simple part which can readily be turned up on a lathe, It is preferably made of steel, smoothly finished or polished, so that it will not-mar or damage the delicate strands of yarn passing beneath the ring.

moving at this speed to a bobbin moving at a' speed somewhat higher than the speed of the yarn. Domng is accomplished by drawing out a loop of yarn, passing it through the slot I S in the support 9, and thus passing it beneath the ring ll and throwing the thread upon the rotating bobbin by a movement of the hand. This threading operation, insofar as throwing the yarn upon the bobbin goes, is similar to the ordinary dofllng with the cap type spinning machines. However, it differs from threading a cap type spinning machine in that the yarn in my improved form .of device is passed through the threading slot is before throwing upon the reel. Thus, in a spinning machine constructed in accordance with my invention, the dofling operation is quite as simple and easy as in the case of cap spinning but, because a light ring is used for ballooning the thread onto the bobbin, the structure does not have the mechanical disadvantages of cap spinning. Moreover, since doiflng can be readily accomplished, my improved floating ring type of spinning device has the advantages of the known traveler type of spinning device.

While I have shown and described preferred embodiments of my invention, various changes can readily. be made without departing from the scope thereof, and I consider as within the scope of my invention all such forms as may come within the scope of the appended claims.

. What I claim is: I

1. In a machine for twisting artificial silk yarn to be used with a rotating bobbin, the combination with a support including an annular seat having aslot extending through the support, of

a ring loosely mounted in the seat and adapted to be held axially of the support therein when in 5 a position of rest, said ring being adapted to float axially in said-seat when yarn is ballooning around the ring as it is being wound on the bobbin, and means'included. in theseat for preventing movement other than axial during the floating movement of the ring.

2. In a machine for twisting artificial silk yarn to be used with a rotating bobbin, the combination with a support including an annular seat having a slot extending through the support, said seat comprising a cylindrical wall and a beveled wall, of a ring loosely mounted in the seat and of a size and shape to be held axially of the seat by the beveled wall when in a position of rest in the seat, the cylindrical wall of the seat being adapted to prevent movement eccentric to the seat axis when said ring is floating in the seat as yarn balloons around the ring in being wound upon the bobbin. c.

3. In a machine for twisting artificial silk yarn to be used with a rotating bobbin, the combination with a support including an annular seat having a slot extending through the support, said seat'comprising a cylindrical wall and a beveled wall, of a ring loosely mounted in the seat, said I ring including a beveled wall and a cylindrical the ring.
